HERCULES SANCI-IE, OF DETROIT, MICHIGAN ELECTRIC CONNECTION.

SPECIFICATION forming part of Letters Patent No. 430,974, dated June 24,1890.

Application filed December 9, 1889- Serial No. 333,100. (No model.) i

To all whom it may concern:

Be it known that I, HERCULES SANOHE, a citizen of the United States,residing at Detroit, county of WVayne, State of Michigan, have inventeda certain new and useful Improvement in Electrical Connections;v and Ideclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

In the drawings, Figure 1 shows my invention applied as a binder orconnection to an ordinary pole-piece, said pole-piece being in thenature of a block or hand-piece with the extreme end closed and with theentering cable shellackcd about the point of entrance to preserve thefabric or covering of the wire from the effects of moisture. Fig. 2shows a similar construction, except that the extreme end is opened.Fig.3 shows its use in connection with a long pole-piece. Fig. 4.illustrates the same in connection with a polepiece which is itselfcharged upon its inte-. rior with filling material: Fig. 5 illustratesthe same appliance in connection with a pad such as may be employed inbelts or bracelets designed for use in connection with an electriccurrent led to it by a line. shows how it may be used for uniting twomeeting ends of stiff wire and avoid the necessity of twisting the wire,there being a screw-threaded swivel interposed between the terminals atthe ends of the wire, so that by turning the parts of the swivel inopposite directions each part may be screwed to its adjacent terminalwithout twisting the wire. Fig.7 shows its application as a terminal forthe meeting ends of flexible wires, where they may be twisted slightlywithout injury to them. Fig. 8 shows the same adapted for thebinding-postof any electrical instrument and adapted to accommodateseveral wires. Fig. 9 shows the same, illustrating how it may beconnected with a plate, and the latter in turn connected to anelectrical instrument and constituting a binding-post. Fig. 10 shows avariation in which the device is adapted as a binding-post forelectrical instruments in ing to the part beneath it by a commonbinderFig. 6.

at the top of the post. Fig. 11 is a view illustrating how the cablecovering or fabric is united to the cable at the point where the fabricis severed so as to prevent its unravel-- ing, the same being shown inconnection with stiff wire. Fig. 12 is a similar view showing the samein connection with a flexible wire cable and illustrating how the finewires of the cable are beyond the fabric wrapped with wire to bunch andconfine them and to make various applications of electricity forburglaralarms, medical instruments of various kinds,

and the like-the ends are very apt to project 1 and are unsightly andliable to catch upon the fingers or the clothes. Again, each time thecircuit is broken the wire has to be unwound or untwisted, and isthereby generally injured or broken. Again, where a cable is employedcomposed of fine wire's-as, for instance, like those connected with thepolepieces orhand-holdsin the variousinstruments used by the medicalprofession, or for connecting the ear-pieces of telephones to thetelephone-box, and the like--the silk or worsted or other fabric withwhich the wire is wound or insulated has to be cut away to bare theterminal end of the cable wires. They are thus loose, and they rapidlyunravel and become unsightly and do not serve to afiord the cable thenecessary insulation and strength at the point of union. Again,the smallwires themselves become tangled and disarranged and are exceedinglyannoying to handle, not only by reason of pricking the fingers, but

because they are not sufficiently stiff to hold in the binding-post.

It is the purpose of my invention to pro-- duce a terminal adapted forconnection to a binding-post, or serving directly as abindinginsulationwinding of silk, worsted, or fabric.

B is a terminal designed for permanent connection with the end of theinsulated wire.

B is a screw-shank, and Z) is an orifice through which the wire ispassed, so that its free end may be wound about this shank.

B is a companion piece into which the shank B is screwed. Either theterminal B or the companion piece B is hollowed out sufficiently thatwhen one is screwed down upon the other the end of the wire iscompletely housed and hidden from view. By winding or coiling the wire Aaround the shank B, as shown, it is made to expose a larger surface tothe companion piece B This companion piece in Fig. 1 is simply a knob,which, together with the terminal B, constitutes a polepiece with itsextreme end closed. In Fig. 2 there is precisely the same construction,except that the screw-shank passes into an orifice which extends throughthe block or companion piece. In Fig. 3 there is a like construction, inwhich the terminal B is engaged with a long pole-piece or companion partB In Fig. 4 there is a similar construction, in which the companionpiece B is itself a polepiece, but is made hollow for the purpose ofreceiving a charge of exciting or other material upon its interior. InFig. 5 the same is shown as applied to the pad of an electric belt orbracelet designed to be .worn upon the surface of some part of the body,the companion piece being made permanent with the pad, or the base towhich the pad is attached. In Fig. 6 there is a similar constructiondesigned for uniting the two meeting ends of the wire,the companionpiece in this instance being two central portions B B swiveled togetherat b This form is particularly convenient, since it enables a union tobe made of the two meeting ends without twisting either end, it beingonly necessary to turn eitherof the swivels B in order to engage itsthread-socket with the threadshank B of its adjacent terminal. This sameconnection (shown in Fig. 6) is also of great value for connecting twoends of wire where the wire is apt to be twisted, for any tendency totwist the wire will simply cause the connection to turn about its swivelfreely. This connection for the two ends of the wire may be made eitherwith the swivel or withenter a corresponding screw-socket in thecompanion piece of the adjacent terminal.

This invention is equally applicable for the permanent or stationarybinding-posts upon the various forms of electrical machines andapparatus. Thus, as shown in Fig.8, each wire has its own terminal andcompanion piece, and when it is desired to connect it with thebinding-post C it is only necessary to drop it over the end of thebinding-post and screw down the jam-nut 0 upon it. is equally welladapted for connection to a plate D, as shown in Fig. 9, in which eventthe'terminal may be bound to a plate, either as shown in Fig. 8, or bya. screw passed down through the top into the plate, as shown in V Fig.9. Of course the form of the device may be somewhat varied. Thus,instead of their being a terminal at the end of the wire connectedpermanently with its companion piece, there might, as shown in Fig. 10,be simply a terminal piece alone, and these terminal pieces might bedropped over the binding-post and be bound to adjacent terminals or tothe post itself without any companion piece.

In order to prevent the insulation winding from unraveling at the pointwhere the wire is bared, I wrap the same with fine wire, as shown inFig. 11. This binds the fag ends of the fabric or winding firmly to thewire, so that it is made perfectly secure at this point. This drawing,Fig.11, shows the said construction in connection with a single stiffstrand of wire; but in Fig. 12 it is shown. as applied to the fine wiresat the end of the flexible wire cable. In this latter case I carry thewinding along to the end of the said fine wire strands, not only to holdthem together, but also by thus bunching them to make this bared end ofwire sufficiently stiff in the nature of a thick strand of wire to holdits own within the binder or terminal. I would have it understood thatthis arrangement of the ends of the wires or wire cables is particularlyapplicable in the devices which are hereinbefore described; but I wouldnot limit myself to their use in connection with said devices, for theyare equally applicable and valuable in connection with any form ofbinding-post or fastening. Wherever it is necessary or desirable, thewire cable may, as shown at a in Fig. 1, be treated with shellac at thepoint where it enters the fastening or terminal piece to protect itagainst the effects of moisture.

which is desired to be perfectly taut withoutv twisting the wire, sincethe ends of the wire may be engaged to the two end pieces and theselatter drawn together by the. turnbuckle swiveled toone end piece andthe screw attached to the other.

What I claim is- 1. The combination of the perforated ter-- minal pieceB, provided with the shank B,

the companion piece B engaged with said shank, and the wire or cable A,passed through the perforation in the terminal piece and coiled aroundits shank, substantially as shown and described.

2. The combination, with the meeting ends of wires or wire cables, of aterminal piece and companion piece on the end of each wire, shanksconnecting; each terminal to its companion piece, the ends of the wiresbeing coiled around said shanks, and a connection between the twocompanion pieces, substantially as described.

3. A connection for the meeting ends of wires or wire cables, the sameconsisting of a terminal piece for each wire, through which the wire ispassed, and two companion pieces swiveled together, each said companionpiece provided with a screw engagement whereby it is united with itscorresponding terminal piece, siibstantially as and for the purposesdescribed.

In testimony whereof I sign this specification in the presence of twowitnesses.
